Create autocomplete/suggestions for customfield in JQL searcher

is there possibility to create autocomplete/suggestions for my own customfields? Let's say I have customfield with name MyCustomfield. I want to be able to write this into the JQL searcher in issue navigator ( "MyCustomfield" = ) and see the suggestions available for this customfield. If so could anyone tell me how or give me some resources as I was quite unfortunate in searching for any resources and instructions how to do it.
